IMPROVEMENT [N STOVE-GRATES.

Specification formin g part of Lettera Patent No.172,822, dated February1, 1876; application filed January 14, 1876.

To all whom it may conaern:

Be itknown that I, GEO. R. MOORE, of the city and county' ofPhiladelphia, in the State of Pennsylvania, have invented n'ew anduseful Improvements in Stove-Grates, which improvements are fully setforth in the following speoifioation, refereneebeing had. to theaccompanying drawings.

The objeet of my invention is to provide such facilities,in oombinatioriwith stove and. hater grates, that ooal-fires may be more easily keptclean.

Figure 1 is a perspective view of the baseseotion of an ordnary stovecontainng a grate in combination with my improvements. Fig. 2 is a planview of the same witli-tbe top plate removed.

A is the easing; B, the grate; C, manual hanger, 10osely jointed ,to thelevers below, upon which the grate is bang, and provided with teet-h 0for holding upon the easing, throngh which it passes at any desiredpoiut.

D is an extensible lever,to be used in lifting 0 when very heavy gratesare used. a is a guide to D, and prevents its aceidental removal fromtheheater.

E F G are conneoted levers, loosely jointed together in triangularform'at their respective ends. E is pivoted at b, ami E at 01. G isprovided With a central socket, whieh receives its counterpart (avertical stem) from the center of the grate. His'a pull-rod forvibrating the grate hori zontally. I is a sx'nall doorway' to the underside of the grate when that is up, and to the upper side of the samewhen it is down, so that a band-poker may be used convenien tly oneithe'r side of the grate by adjusting it as required.

The operation of the levers is sueh that the grate is carried up anddown upon a horizontal level as longas the front ends of E and G arekept together, as in this case; but the front ends ofE and G may be leftfree, and

moved separately, and the grate then carried upflor down, so as toincline ether way at w1 o It is easierstarting .fire,and less kindlingsare required, when the grate is up, so that but little air can pass intothe fire-ohamber without passing through it; but when the refuseproduots of oombustion are to berennove'd the operation is more rapidlyand easily done by dropping the gratedown, and then vibratng it rapidlyit Will disoharge its load over -its periphery..

I am'aware thai: it.is usual todrop some part of a grate, or even thewhole of it, in order more eonveniently to get at the fire to clean itbut my improvements are seen in the deviees I have brought together aiidcom bined for doing this.

I have had regard to preservin g a elear space around the grate; also,tothe woidanee of ust.

The whole ofieration may ordinarily be performed. without opening anyparl of the heat' er. .The aperture's through whih the rod H and thehanger 0 pass will not allow the es upon the adjustable levers, asshoW'n, the rod H, as and for the purpo se herein set forth.

3. The manna] hanger O, in combination With the levers E F G,substantially as shown.

4. The extensible lever D, in eombination With the hanger C,substantially as shown.

.5. In eombination,the heater-base A, grate B, and. levers E F G,substantially as Shown.
